CLAMP.

Application led April V22, 1921. Serial No. 463,518.

To all 'whom z't may concern:

Be it known that I, JOSEPH GENTILE, a citizen-of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Clamps, of which the` following isl a specification.

This invention relates to improvements in clamps. V

The primary object of this invention is to provide'an effective Vclamping device particularly adapted to clampror bind the end of a flexible tube to a gas source, or appliance or fixture in such manner as to prevent the escape of the gas at the place where the tube is connected to the object, and also to prevent the accidental disconnection of the tubeI from the Object to which it is connected.

Another object of this invention is to provide a spring clamp having a duplex clamgp- .ing element and binding or spring elements disposed at 'the ends thereof for `facilitating its binding or clamping effect.

These and like objects,such\ as convenience in operation, cheapness of construction and neatness of appearance, are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a view showing an application of the invention at both ends of a flexible tube.

Figure 2 is a front elevation of same.

Figure 3 is an end elevation of same.

Figure 4 is a plan view of the blank from which the frame is formed.

Fi re 5 is a plan view ofthe blank from whic the binding elements are formed.

Figure 6 is a transverse sectional view of one of the binding elements.

Fig. 7 is a view of one of the clamp screws.

Stated briey in general terms, the invention comprisesa frame bent and shaped so as to form a duplex clamping element, a pair of binding or spring elements removably secured within the clamping element at the latters ends and clamp screws adapted to increase or diminish the binding effect of these elements.

Referring now to the drawings in detail there is ldisclosed a frame 11 having its center portion 12 stamped in a suitable pattern so as to make the device light in weight and attractive in appearance.

This frame is made from a blank cut from a thin sheet metal plate or other suitable material by executing suitable bending, shaping and similar operations thereupon, by nreans of suitable dies, so as to cause the blank to assume the forni of the finished frame.

Figure 4 shows the frame flattened out but theV blank from which the frame is formed may depart somewhat from this shape, so long as it serves fthe purpose required of itin this invention.

When frame 10 assumes its finished form it has a substantially cylindrical shaped body 13.V Each end of the frame is provided with a pair of spaced ears 111 projecting downwardly fromand made integral with the wallof thebody. One ear of each pairA41 has an annular perforation 15, the other ear being provided with a slotted perforation 16, the formerbeing in alinement with the latter so as to receive a screw 17. Screws 17 are provided with shoulders 18, which engage slotted perforations 16 so as to prevent them froml turning with wing nuts 19 when thelatter 'are manipulated to bring the ears closer together. f l

Binding elements 20 are made from suitable blanks of spring steel formed to desired shape by means of suitable dies. Figure 5 shows one of the blanks after being stamped and Figure 6 shows same after being bent and shaped to the desired form.

The upper portion 21 of each bindin element 20 is shaped so as to conform to ody 13 of frame 11, and the free ends 22 and 23 of which are spaced apart. Tongue 24 is cut out of the blank and has a perforation 25. This tongue is bent downward and has an upturned hook portion 26 formed at its end. When placed in position, upper portion 21 of each binding element 20 engages the inner wall of body 13, while its tongue 24 lies parallel with one of the ears 14, and upturned hook portion 26 of said tongue is in sliding engagement with the free end of the ear. When binding element 20 is in this position perforation 25 alines with perforations 15 and 16.

Figure 1 illustrates how the spring clamp may be employed. One end of flexible tube 27 is passed through the clamp and connected to the gas cock 28, and the clamp adjusted so that one end engages the nozzle of the as cock and the other end engages the flexible tube. Then by turning wing nuts 19 upon screws 17 in the proper direc y to a faucet.

tion ears 14 of frame 10 areibroughtcloser together, shoulders 18 of screws 17p,preventing the latter from turningby''being in en-V gagement with slotted perforations 16.

As ears 111 of frame 10 are brought clos-er:

together in the manner described above, the diameter of upper portion`21 of each'binding or spring element 2O decreases, ,its free ends 22 and 23 being forced to come closer together. Consequently; the nozzle ofthe gas cock andthe end ofthe flexible tube are gripped by the binding elements and prevented from being accidentally separated. Binding elements 2O are held in position by means of screws ,17,v the latter passing through perforations 25 in tongues 24:, and hook portions 26 which slidingly engage the free ends of earslt. 4

A similar spring clamp is used at Athe other end of the flexible tubezto Isecurely clamp ,the latter to the fixture. v

Thel spring clamp above: described may also be adapted to clamp a Watering ,hose

From the foregoing it will be seen that aV neat, convenient and effective i spring "clamp has been disclosed which will prevent the accidental disconnectionofa ,tube from the object to which it is connected and also prevent leakage at the connecting point.

While a preferred embodiment of this invention hasbeen showny and described it will be understood that chan es in the form,

arrangements, proportions, sizes and details u thereof may be made with`o11t departing sco-perofzthe invention as vdescribed.

in the appended Claim..

'l Having'lthus described my invention Whatl desire to secure by Letters Patent and claim, is

"A clamp comprising a frame` having a cylindrical-shaped body, said frame being provided at either end With a pair of spaced ears projecting L"from and made integral with the Wall of said body, one ear of each pair being provided 4With anannular perforation and the othervvith 'a slotted perforation, pair of binding elements Veach of which having annpper'portion disposed Within and conforming in shapewvith, said body butvhaving itsfree ends spaced apart, each of said ,bindingelements being provided With a tongue portion bent upwardly at its freev end so as tol engagean ear of each pair, said tongne having a perforation in .allument vvvithj the perforations in said ears-,- clamp screws adapted to engagethe perforations in said ears and tongues, Vsaid screws being provided with shoulders at Y ltheirfhead portionsrvvhich are Vadapted to cengage the slottedperforations in said ears,
